- the control of the utility vehicle 100 can take place in various ways from the guide vehicle 200 with the aid of the environmental sensors 102, 212, 330.
- the guide vehicle 200 sends control instructions (also: control specifications) for transverse and longitudinal guidance to the utility vehicle 100 (e.g. steering wheel angle, steering angle, speed, acceleration).
- the control instructions can also be generated by a driver actuating the steering wheel and pedals in the guide vehicle 200.
- the lead vehicle 200 does not implement the control instructions itself, but remains at a standstill.
- the lead vehicle 200 forwards sensor data from the environment to the utility vehicle and allows the utility vehicle 100 to process the sensor data.
- the guide vehicle 200 can intervene in critical situations via stop or abort signals.
- the guide vehicle 200 drives forwards and backwards, the utility vehicle 100 keeping the distance from the guide vehicle 200 constant, as in the case of a trailer (“virtual drawbar”).
- the guide vehicle 200 can use environment sensors 212, 330 to ensure safe operation of the environment, in particular when reversing, and / or maneuver the utility vehicle 100 in a targeted manner.
